Automobile shock absorber oil spills or old oil spill, imprinted checksAuto shock absorber in case of oil leakage, shock absorbers, will no doubt be a very dangerous thing. Then, once a leak is found, it is necessary to make timely remedial measures. Shenzhen rental airport car rental car rental car rental car rental checks focused on projects in the exhibition oil seal gaskets, gasket burst damage, water storage cylinder, check whether these parts appear nut loose.
If the oil spill, first tighten the cylinder nut, shock absorber oil spill, the failure of oil seal, gasket may be damaged should be replaced with new seals. Shenzhen rental car rental car rental airport car rental rent a car if you still cannot remove the exhibition oil spill, should pull the vibration reduction, if there is a credit card or do not weigh a further check that the clearance between the piston and the cylinder is too large, shock absorber piston rod bent, surface of the piston rod and cylinder for scratches or marks.
If the damper is not leaking, you should check the shock absorber connecting pins, connecting rods, connecting hole, rubber bushings are damaged, unsoldering, cracking or shedding it. Shenzhen car rental car rental business car rental airport car rental exhibition car rental if above check normal, is should further decomposition shock absorber, check piston and cylinder tube between of tie clearance whether had big, cylinder tube has no pulled injury, valve sealed whether good, valve flap and valve seat fitting whether closely, and shock absorber of done spring whether had soft or broken, according to situation take repair mill or for pieces of approach repair.
in addition, appear in the actual use made a noise of shock absorber failure, this is mainly due to the shock absorber collide with the leaf springs, frame, or axis, pad is damaged or fall off and boot for shock absorber tube deformation, oil causes such as inadequate, the reasons should be identified and repaired.
check shock absorber repair work should be carried out on a special test rig test, when the frequencies of resistance at 100 ± 1mm, its resistance shall conform to the provisions of the access to stroke and compression stroke. Drive maximum resistance to 392~588N; Dongfeng vehicle access to travel a maximum resistance of 2450~3038N, compression stroke maximum resistance to 490~686N. If no test conditions, we also can used a experience practices, that with a iron wear into shock absorber bottom rings within, with double feet stepped on live its ends, hands hold Shang rings reciprocating pulled 2~4 times, dang up pulled Shi resistance is big, down pressure Shi not was effort, and stretch of resistance and repair Qian compared has recovery, no empty drive sense, is showed that shock absorber basic normal.
